I agree, probably the "Hang" test, where they check RF compatibility and rattle the payload by driving it around. Luis, do you know what payload this is?

Re: NASA Balloon over Ft. Sumner, NM (again)

ADS-B is showing barometric altitude while APRS reports GPS altitude. At high altitudes, the difference is significant as you pointed out.  Some of the web sites such as flightradar24.com will show "Geometric Altitude" or GPS altitude as shown below.

Luis,

The ADS-B shows a descent rate of more than 2,000 ft/min  while NASA  (at 19:02 UTC) shows a 54 ft/min descent.  NASA now (19:42 UTC) shows it in descent at more than 2,000 ft/min.  Did you look at the ADS-B after the NASA page and happen to catch the balloon just a few minutes after termination?

Can someone explain me the reason for the difference between onboard altitude reading and ADS-B altitude reading in the same balloon flight? While NASA shows it's balloon at 106.000 ft the ADS-B shows it at 89.000 ft. Anyone? please?

Balloon has been at float about 108,000 feet for several hours Looks like they may be ready for termination. Plane C441 is criss-crossing in balloon path. ADSB on N372NA is on FlightRadar.

How much ya know about HF amps? I need to slightly re-design the output network of an old Heathkit SB-220.

I have been reading a Lot about how these networks things are designed, and the more I read the more I am in a fog about it.

If you think you might be able to help I'll send ya the details.

if this has not happened I would be amazed.

A Balloon flight is in the works, and I don't have anything for APRS well at least anything compatable with the new computers like old MFJ tnc's not sure if it even works, or actually where it even is.

Re: APRS

Michael Hojnowski
 

Joe,

If all you wish to do is decode, and/or iGate, a cheap and easy solution is to pick up a $20 SDR dongle, and run Direwolf on Windows / Mac / Linux.  I recommend that for student groups I work with when they're flying APRS trackers.

Re: APRS

Garrett, Mark
 

Joe:
Go find that MFJ in all of "your stuff" as it will work to decode your payload.  Probably will need a copy of Hyperterm or something similar to view the data.
